I test audio products for a living, and between Sony's WH-1000XM6 and Bose QC Ultra Headphones (2nd Gen), this is what I think you should buy

A hands-on comparison says Bose QuietComfort Ultra Headphones (2nd Gen) edge out Sony WH-1000XM6 for comfort and portability.

Sony WH-1000XM6 counters with more features, including LDAC support, a tighter fit, and broader connectivity options.

Both are premium ANC travel headphones, so battery life, codecs, controls, and case size may decide the better buy.

The choice comes down to whether you value Bose’s easier all-day wear or Sony’s richer feature set.
